SHUTTLE.

SPECIFICATION formingpart of Letters Patent N 0. 719,685, dated February3, 1903. Application filed November 3, 1902. Serial No. 129,803. (Nomodel.)

To all whom it may concern:

Be it known that I, JOSEPH H. MORIN, a citizen of the United States,residing at Wilkinsonville, in the county of Worcester and State ofMassachusetts, have invented certain new and useful Improvements inShuttlespf which the following is a specification.

My invention relates to a shuttle, and particularly to the threading ofa shuttle or the drawing of the free end of the thread or filling-weftfrom the bobbin through the eye of the shuttle preparatory to using theshuttle in the loom.

In the ordinary construction of a shuttle the free end of the thread issucked or drawn through the shuttle-eye by the mouth of the operator.

The object of my invention is to do away with the sucking of the threadthrough the shuttle-eye and to provide a device to be applied to andsecured in the shuttle-throat by means of which the shuttle is threadedby hand.

I am aware that there are self-threading shuttles which aresubstantially automatic in operation and are particularly designed to beused in what are termed automatic looms. In these shuttles the side ofthe shuttle at the threading end is slotted or out down to allow of thefree passage of the thread. My improvements do not relate to this classof selfthreading shuttles.

In my improvements the threading device is preferably made of sheetmetal in one piece cut and formed into the desired shape. A part of thedevice forms the eye for the thread where it passes through the side ofthe shuttle, and thus the use of the ordinary eye is dispensed with.

In using my improvements the shuttle has a hole or opening through itsside at one end for the thread to pass through,as is customary; but theside of the shuttle is not slotted or cut down, as is the case inself-threading shuttles, as above mentioned.

My invention consists in certain novel features of construction of myimprovements, as will be hereinafter fully described.

' Referring to the drawings, Figure 1 is a plan view of the delivery endof a shuttle with my improvements applied thereto. Fig. 2 is a side viewof the end of the shuttle shown in Fig. 1 looking in the direction ofarrow 01,, same figure. Fig. 3 is a vertical cross-section on line 3 3,Fig. 1 looking in the direction of arrow I), same figure. Fig. 4 is aperspective plan view of my threading device detached. Fig. 5 shows theblank from which my threading device shown in Fig. 4 is formed. Fig. 6is a side view of the threading device shown in Fig. 4 looking in thedirection of arrow 0, same figure; and Fig. 7 is a perspective plan Viewof the tension mechanism for the thread removed, showing the felt andspring.

In the accompanying drawings,l is the shuttle-body, which may be of theordinary shape and construction, with one side longitudinally grooved orrecessed, as shown at 1, and a perforation or opening 1 therethrough forthe passage of the thread 2 from the bobbin 3 on the spindle 4, as iscustomary.

The shuttle-body 1 is cut out or recessed at its delivery end to receivethe threading device 5. (Shown detached in Fig. 4.) The threading device5 is preferably made from one piece of sheet metal stamped or cut out bya die or otherwise into the blank shown in Fig. 5, which is bent orpressed into the shape shown in Fig. 4.

The threading device 5 is of loop shape, as shown in Figs. 4 and 6, andconsists of the fiat or base portion and the upper part for guiding thethread. The flat or base part (1 extends within and rests upon therecessed or cut-out portion in the body of the shuttle and is securedtherein by a screw 6, extending through a hole I) in the base a. Accessto the head of the screw 6 to turn the same in or out is obtainedthrough the slot or perforation c in the upper part of the threadingdevice 5, which extends to the base part a, and one edge of thethreading device 5 at the loop portion is slotted, as shown at d, Fig.4, to receive the thread 2. The inner end of the slot d is in line withthe end of the spindle 4, as shown in Fig. 1. On one edge of thethreading device 5 is the lip or extension e, which in forming thedevice 5 is bent upwardly and then downwardly at its free end to extendover the upper side of the threading device 5, as shown in Fig. 4. Thelip or extension 6 forms with the loop portion of the device 5 the eye ffor the passage of the thread 2. (See Figs. 2 and 6..) The eyefislocated at the opening 1" in the shuttle-body 1, as shown in Fig. 2, andforms the deliveryeye for the shuttle.

The free end g of the upper thread-guiding part g of the threadingdevice 5 is of reduced width and bent upwardly, as shown in Fig. 5. Theedges of the upper part 9 are inclined or tapering, and one edged isnotched at t". (See Fig. 4.)

In connection with the threading device 5 shown in the drawings andabove described I prefer to use a tension device for the thread; butthis is not necessary, and my threading device 5 may be used with orwithout a tension.

I have shown in the drawings a tension device combined with thethreading device 5, which in this instance consists of a piece of felt7, located in the shuttle-body l, in front of the threading device 5,and a spring-blade 8, which has a hole 8 therein and is secured in theshuttle-body outside of the threading device 5 by a screw 9, as shown inFig. 1. The free end of the spring 8 extends through the lower end ofthe perforated part c in the upper part of the threading device 5 andbears on the felt 7, extending within the threadingdevice, (shown inFig. 4,) and in this way puts a tension on the thread 2 as it is drawnfrom the bobbin3 through theeye fof the threading device 5.

The tension on the thread may be varied by turning in and out the screw9, which holds the tension-spring 8.

The operation of my threading device will be readily understood by thoseskilled in the art.

The free end of the thread from the bobbin is passed under the upwardly-bent end 9 of the upper part of the threading device 5 and is drawndown along the edge 2'. (See broken lines, Fig. 4.) The other portion orloop of the thread moves over the upper part of the device 5 and on itsother edgej and finally slips over the edgej and enters into the slot d.The free end passing along the edge 71 enters into the notched portion tand passes under the lip 6 into the eyef, as shown in Fig. 4, with thefree end extending into the cutout portion in the body of the shuttle.The loop of'thread formed at the eye portion is then grasped by theoperator and drawn out to bring the free end outside of the shuttle, asshown in the drawings. In case the tension-spring Sis used the free endpasses down under the free end of the spring 8 and over the feltextending under the spring, as shown in Fig. 6.

The advantages of my improvements will be readily appreciated by thoseskilled in the art. My threading device is of simple construction, andin its use the shuttle-body is not slotted or cut down on the side ofthe delivery end and the ordinary the side of the shuttle is not eyefitted into required, and

my threading device may be combined with any ordinary form of shuttle.

It will be understood that the details of construction of my threadingdevice may be varied, if desired, and it may be used with or without thetension-spring for the thread.

Having thus described myinvention, What I claim as new, and desire tosecure by Letters Patent, is
